Ball Bearings
Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.
Sealed bearings block out dust and other contaminants better than open and shielded bearings, but retain the most heat.

Permanently Lubricated Ball Bearings
A solid polymer lubricant surrounds the balls, eliminating the need for additional lubrication. Because it's solid, the lubricant blocks out water and dust, extending the life of the bearing.
Sealed bearings have even better resistance to dust and contaminants than open bearings.

Needle-Roller Bearings
Also known as drawn-cup roller bearings, these are our thinnest roller bearings. The outer ring is drawn out to form a lip that holds the bearing together. Bearings take on the shape of their housing and may be oblong prior to installation.
Open bearings dissipate heat more efficiently than sealed bearings.
